SAME PLACE,

BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters-Patent No. 570,121, dated October27', 1896. Application filed September 6, 1895. Serial No.v561,626. l(Nomodel.)

To @ZZ whom t may concern:

Beit known that I, KARL BUXBAUM, a subject of the Emperor ofAustria-Hungary, residing in the cityand county of Philadelphia, Stateof Pennsylvania, have invented a new and'useful Improvement in BindingAttachments for Sewing-Machines, which improvement is fully set forth inthe following` specification and accompanying drawings.

My invention consists of a binding attachment for a sewing-machine whichis formed of novel parts, as will be hereinafter1 set forth, and pointedout in the claims that follow the specification.

Figure l represents a perspective View of a bindingattachment or deviceembodying my invention. Fig. 2 represents a longitudinal section thereofon line am, Fig. l. Fig. 3 represents a Vertical section of a portion online y fy, Fig. l. Fig. e represents a horizontal section of a portionon line e a, Fig. l. Fig. 5 represents a vertical section of a portionof the base or bed plate with a leveling-screw therein.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the base of the device, the samebeing provided with slots Al for attachment to a sewing-ma chine.

On the side of the base A is the arm B, the outer end of which has vthegrooved gage O thereon, and the inner end has the limb D therein, saidarm B being freely connected with the base A by the screwE, which passesthrough the slot E and enters said base.

F designates a screw which passes through the limb D and enters the baseA at a right angle to the screw E, whereby the arm B, and consequentlythe gage O, may be adjusted to and from the folders I-I and J, saidscrew F also carrying the jam-nut G for evident purposes.

The folders I-I and J consist of plates J J 2, with inturned lips, theplate J being adjustably attached to the base A by means of the screw Kand pinfL, while the plate J 2 is vpreferably rigidly attached to thebase A by the screws or rivets, it being noticed that the gage O is setback of the lips N of the folders.

In the plate J are slots P and Q, through which the screw K and pin Lpass, respectively, by which provision said plate J may be moved inopposite directions for adjusting the folders relatively to each other.

On the pin L is a washer R, which rests upon the plate J and is pressedagainst the same by means of the spring S, which is interposed betweensaid washer and the nut T, the latter being fitted to the threadedportion of the pin L, by which provision the tension of the plate J maybe adjusted, said plate being elastic or yielding.

In the base A are vertically-arran ged screws U, whose points,which arebelow, are rested on the plate of the sewing-machine, so that said basemay be set true on said plate.

V designates an arm which is connected with the journal WV, the latterfreely entering the socket X on the base A, so that the arm may beraised and lowered or vertically adjusted, said journal being adaptedtobe engaged by the screw Y, so as to retain said journal, andconsequently the arm V, in adjusted position.

Rising from the armVand secured thereto is a guide Z, consisting of thecolumns Z', between which is a slotted gage B', through which passes thescrew C', so that said gage may be raised and lowered relatively to thewidth of the band or binding material, the screw being provided with thehead D' and nut E', whereby the gage may be clamped and thus held in adjusted position.

The armV carries at its outer end the platespring F', which-partlyenters between the columns Z' and is adapted to bear against the band orfabric Gr', (shown in full lines in Fig. l and dotted lines, Fig. 3,)said spring being engaged by the screw H for adjusting the pressure onthe spring and consequently on the. band or fabric.

The operation is as follows: The binding material is passed through theguide Z, with the gage B thereover, so that said material moves true anduniform through said guide, its tension being regulated by the spring Fthrough the medium of the screw H', as has been stated. The bindingmaterial, with the fabric between the same, is now directed through thefolders N, and the material is properly turned over the fabric, and thetwo IOO are now 'conveyed to the needle of the niachine, whereby thebinding is stitched tothe fabric. 1When the fabric or binding, or both,is of increased thickness, the plate J' yields, and when the fabric orbinding, or both, become normal said plate returns to its originalposition, owing to the action of the spring S and the elasticity of theplate JC Vhen it is desired to have fabric bound with material ofgreater Width on one side than the other, the plate J is moved out, sothat its lip N eX- tends outwardly to a greater extent than that of theplate J2. v

The plate A is shown With a duplication of parts, such as the folders,gage, adjusting features, &c., which `may be of different sizes from thecorresponding parts if so desired, so as to adapt the attachment to thebinding of materials of different dimensions, thus avoiding theemployment of separate attachments for such purpose.

rIhe device is serviceable for binding clothing, hats, and garmentsgenerally, suspenders, and other articles.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. In a binding attachment a plate, a gage having a slotted side armwith a limb at its end, an ad justing-screu7 in said limb and plate, anda clamping-screw in said arm, said parts being combined substantially asdescribed.

2. In a binding attachment, a plate with a horizontal socket in itsfront end, an arm having a journal adj ustably mounted in said socket, aguide secured to said arm, and a gage supported on said guide, saidparts being combined substantially as described.

In a binding attachment, a plate with a horizontal socket in its frontend, an arm journaled lin said socket, a clamping-screw for the journalof said arm, a guide secured to said arm, a gage supported in saidguide, a spring secured to said arm, and means for controlling saidspring, said parts being combined substantially as described.

4c. 'In a binding attachment, a main plate with a horizontal socket inits front end, folders on said plate, an arm with journal adjustable insaid socket, a guide consisting of standards secured to said arm, a gageadjustable in said guide, and a spring with an end in said guide, saidparts being combined substantially as described.

5. In a binding attachment, the arm V having the journal IV mounted inthe socket X, in the base thereof, the guide Z on said arm, the gage B',in said guide, the spring F on said arm adjacent to said guide, and theset-screw Il', in the arm and engaging said spring, substantially asdescribed.

KARL BUXBAUM.
